Better and simpler solution: Create a Bitcoin address and send one Satoshi to yourself every month.
When the transactions stop, people know you are dead.
This way you need no trusted third party, no special software, no special contract.

Suppose you're a whistleblower, who exfiltrated gigabytes of unredacted data from the NSA. So far you've leaked only redacted excerpts, but the NSA might kill you to stop your leaking.
However, the NSA really doesn't want the whole archive leaked, or it would blow their agents' covers.
So, you put the whole archive up on the net, encrypted, and set up Killcord to decrypt unless you keep checking in. This keeps you alive, since the NSA knows it'll leak if you're dead.
I am in the early stages of building a "providers" abstraction for killcord so that backend, publisher, etc are plugable. Using this bitcoin pattern for check-ins could be really cool.
